FINGER-RING.

SPECIFICATION forming part of Letters Patent No. 516,211, dated March 13, 1894.

Application tiled July 24, 1893. Serial No.1181.366. (No model.)

To all whom, t may concern,.-

Be it known that I, CHARLES M. LEVY, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Finger-Rings, of which the following is a specification.

My invention relates to an improvement in nger rings of the class wherein the setting retaining pin.

or stone is adapted to be removed from the gem box to be replaced by another having a different design or ornament on its outer surface, and the object of my invention is to provide means for holding the setting which shall be cheap, effective and compact, and which firmly holds thesetting from edge to edge and entirely across the stone, thus obviating all danger of the stone becoming loose and rattling in the box.

My invention consists in providing the under surface of the stone with a plate of metal, hard rubber, Celluloid, or other suitable material over which, between it and the stone, a retaining pin, or strip of metal passes the ends of which pin enter coincident apertures or seats in the walls of the box.

,In the accompanying drawings to which reference is made-Figure 1 is a disassembled perspective view of a finger ring embodying my invention. Fig. 2 is an edge view of the ring. Fig. 3, is a sectional view taken in line of Fig. 2, showing a modified form of Fig. 4 is a transverse sectional View taken in line y, y, of Fig. 3.

A represents the body of the ring forlned with a gem box A to receive the setting or stone B, to the outer surfaceof which is applied an initial or other ornament, as shown in Fig. l. Two of the opposite walls of the box are formed with apertures a a' to receive a retaining pin C. This may be a plain pin or rivet, as shown in Fig. 3, in which case the aperture o. will be plain and of the same size as the aperture a, or it may be formed with a short screw a2 at one end, in which latter case the aperture a will be enlarged and screw-tapped, as shown in Figs. l and 2.

The setting or stone Bis preferably curved and is provided upon its under surface with a plate D preferably of metal, though hard rubber, Celluloid, or other suitable material may be employed. edge to edge of the stone,'and overit, between it and the stone, the retaining pin C passes being inserted through the apertures a. a'. The said plate is beveled at its edges and is formed with a channel d', along its upper surface to receive the retaining pin and form a seat therefor throughout the whole length of the plate, and the plate is held to the stone by being inserted in a dovetailed groove B formed in the undersurface of the stone. At the center of the dove-tailed groove and the whole length thereof, the stone is also channeled, as shown at b to embrace the upper part of the retaining pin, while the lower part rests in the groove d in the plate D.

I am aware of the patent to Harry Lehr, dated October 16, 1888, No. 391,057, wherein the setting is formed with a dovetailed groove in which is fitted a plate formed with loops on its under surface, and wherein the gembox is also formed with upwardly projecting loops and its side walls with apertures through which, and through the said loops, a retaining pin passes for holding the setting in place and I lay no claim to such construction. By myinvention the setting is held exclusively and directly by the plate and pin and the gem-box is made very shallow, that is no deeper than the thickness of thesetting and the bottom of the setting and plate are iush with one another and rest upon and are supported by the bottom of .the gem-box which adds greatly to the stability of the ring and prevents the breaking or cracking and shifting of the stone.

By this construction, the-stone is firmly held at all times in the gem box and is uniformly held at all parts; besides the construction is cheap and practical.

Having thus described my invent-ion, what I claim as new, and desire to secure by Letters Patent, is-

l. The setting formed with a dovetailed groove in its under surface and a plate fitted in said groove and the gem-box having apertures in opposite walls thereof, in combina- This plate reaches from tion with a retaining pin passed through said its upper surface, in combination with a reapertures and between the said plate and settaining pin constructed and operated substan- Io ting substantially as described. tially as and for the purposes described.
